Visceral ischemia caused by acute aortic dissection following blunt aortic injury: report of a case.
The diagnosis and management of blunt thoracic aortic injuries have seen significant changes over the last decade. The purposeful delay of definitive repair by aggressive blood pressure management has been suggested to be safe, and deliberate nonoperative management may be a reasonable alternative in selected patients with minimal aortic injuries detected with contrast-enhanced computed tomogra...
OBJECTIVES Reference values of aortic deformation during the cardiac cycle can be valuable for the pre-operative planning of thoracic endovascular aortic repair (TEVAR) and for facilitating computational fluid dynamics. This study aimed to quantify normal aortic extensibility (longitudinal extension) and distensibility (radial expansion), as well as pulsatile strain, in a group of 10 (>60 years...
a 32-year-old female patient with previous bentall operation and mitral valve repair surgery due to severe aortic insufficiency, mitral valve insufficiency, and ascending aortic aneurysm was admitted to our hospital with serious dyspnea, fatigue, and mild chest pain. two-dimensional echocardiography demonstrated a markedly dilated basal aorta and cardiac chambers. thoracic computed tomography s...
Aortic aneurysms can be classified into thoracic & abdominal aortic aneurysm with different clinical features, diagnostic characteristics and management. If the growth occurs continuously, it can result in bursting of the artery and bleeding, a condition termed aortic dissection, which is considered a catastrophic fatal condition. Abdominal aortic aneurysms are generally caused due to infection...
Gene mutations that lead to decreased contraction of vascular smooth-muscle cells (SMCs) can cause inherited thoracic aortic aneurysms and dissections. Exome sequencing of distant relatives affected by thoracic aortic disease and subsequent Sanger sequencing of additional probands with familial thoracic aortic disease identified the same rare variant, PRKG1 c.530G>A (p.Arg177Gln), in four famil...
OBJECTIVES Brahma-related gene 1 (BRG1) and long non-coding RNAs (lncRNAs) play important roles in cellular processes. However, little is known regarding their roles in thoracic aortic aneurysms. We investigated BRG1 expression in thoracic aortic aneurysms and the roles of BRG1 and the lncRNA HIF 1 alpha-antisense RNA 1 in regulating the proliferation and apoptosis of aortic smooth muscle cells...
BACKGROUND Acute descending thoracic aortic dissection is a life-threatening emergency. It is not often considered as the initial diagnosis in patients presenting with epigastric pain and could easily be missed in a busy casualty department. AIM This case report is aimed to highlight the feasibility of the technique and the need for long-term surveillance following endovascular repair of acut...
Helically cut thoracic aortic strips (from rats, rabbits, and guinea pigs) in a state of low to moderate tone and under the influence of alpha-receptor blockade relaxed in response to isoproterenol. Propranolol blocked these relaxations. Helically cut thoracic aortic strips from cats and abdominal aortic strips from rats, rabbits, and cats were not relaxed by isoproterenol. In addition, aortic ...
BACKGROUND Pulse wave velocity, conventionally determined between the carotid and femoral arteries, is a useful measure to estimate stiffness of the aorta. We investigated local pulse wave velocity (LPWV) in different segments in the aorta with relatively early-stage atherosclerosis in relation to the extent and severity of atherosclerotic lesions. METHODS Pressure waves were recorded in eigh...
RATIONALE Mutations in several genes have been identified that are responsible for 25% of families with familial thoracic aortic aneurysms and dissections. However, the causative gene remains unknown in 75% of families. OBJECTIVES To identify the causative mutation in families with autosomal dominant inheritance of thoracic aortic aneurysms and dissections. METHODS AND RESULTS Exome sequenc...
